FINGER-BAR-ADJUSTING DEVICE FOR MOWlNG-MACHINES.

SPECIFICATION formingpart of Letters Patent N 0. 702,433, dated June 17, 1902. Application filed February 15. 1900. Serial No. 5,264. (No model.)

To all whom it mayconcern:

Be it known that 1, CHARLES G. HUNTER, a

citizen of the United States, residing at Lawrence, in the county of Marion and State of Indiana, have invented certain new and use-. ful Improvements in Finger-Bar-Adjusting Devices for Mowing-Machines, of which the following is a specification.

In mowing-machines as the joints by which compensated for and the proper alinement.

between the finger-bar and the direction of motion or path of travel of the cutter-bar be preserved or restored.

A machine embodying said invention will be first fully described and the novel features thereof then pointed out in the claims.

Referring to the accompanying drawings, which are made a part hereof and on which similar reference characters indicate similar parts, Figurel is a perspective View of a mowing-machine, otherwise of a well-known form, embodying my present invention; Fig. 2, a top or plan View, on an enlarged scale, of the heel or inner end of the finger-bar and cutterbar and immediately adjacent parts, that be ing the point where the mechanism of my invention is located; Fig. 3, a detail top or plan View of the adjusting devices and immediately adjacent parts separately, on a still further enlarged scale, as seen from the dotted line 3 8 in Fig. 4; and Fig. 4, a detail sectional view as seen from the dotted line 4 4 in Fig. 3.

The essential feature of my invention, as will by this time be readily understood, consists in carrying the finger-bar by two points of attachment, one of which is adjustable, so that the position of said finger-bar can be adjusted from time to time by swinging the outer end or point of the finger-bar forward or back to bring it into proper alinement with the direction of stroke of the cutter-bar carrying the cutter-sections or sickles.

In the construction illustrated in the drawings the finger-bar l is attached rigidly to the shoe 2 and in which the adjustment is effected between the shoe (which is thus substantially integral with the finger-bar) and the frame part 3 carrying the same. This frame part 3 is bifurcated, and its two branches are pivoted, respectively, to bearing-blocks 4: and 5 by means of ordinary hinge-pivots, as shown. The bearing-block 4 is or may be secured rigidlyto the shoe 2 in an ordinary and wellknown manner and needs no special description. The base of the bearing-block 5, however, is provided with adjusting-slots and is held to the shoe2 by means of bolts or rivets 6 and 7, secured in said shoe and passing up through said slots, as best shown in Figs. 3 and 4.. Attached to or forming a prolongation of the base of the bearing-block 5 is a screwthreaded rod 8, which passes out through a suitable perforation in a lip 9, formed on the shoe 2, and is provided with a nut 10 on its outer end.

The operation is as follows: When the finger-bar becomes disarranged or out of alinement, so that a new adjustment is desired, such adjustment is easily efiected by loosening the nuts on the bolts 6 and 7 and,adjusting the parts by means of the nut 10 on the screw-rod 8 until the proper relative position is secured, when by tightening down the nuts on the bolts 6 and '7 again the said parts are accurately and firmly secured in adjusted position, and,as is obvious, this may be done repeatedly and as often as becomes necessary or is desiredwithout taking out the cutterbar or disassembling the machine in any way or interrupting the work for more than a few moments.

Having thus fully described my said invention, what I claim as new, and desire to secure by Letters Patent, is-

1. The combination, in a mowing-machine, of the fin ger-bar, the shoe, the frame to which it is attached, two attaching-joints one on each side of said finger-bar, oneof said attaching-joints being mounted to be adjusted longitudinally in relation to the finger-bar, whereby said finger-bar may be alined with screw-rod whereby an adjustment of the finger-bar relative to the parts to which it is attached maybe secured,substantially as shown and described.

In Witness whereof I have hereunto set my hand and seal, at Indianapolis, Indiana, this 10th day of February, A. D. 1900. 1
